When creating an ElasticSearch output connection, the connection status says:
Lookign at elasticsearch logs I see the following error:
A google search for "No feature for name [_status]" led me to ES documentation (https://www.elastic.co/guide/en/elasticsearch/reference/2.0/indices-status.html) that states:
The index _status API has been replaced with the Indices Stats and Indices Recovery APIs.
Looks like Elastic connector for ManiFoldCF is out of date and needs fixing.
NOTE: the connector still works in terms of pushing data to Elastic, despite the error.
I have created a StackOverflow question/answer http://stackoverflow.com/questions/35281379/manifoldcf-error-when-creating-elasticsearch-output-connector - if possible please update once it's fixed.
